LT4, C7R (LS7) pics from NAIAS

Thought I'd share:

LT4 Engine. I had to reach my phone around the display so they might be a little random.

Cool photos, thanks for sharing. I love that LS7.R

If you have the chance, could you pull those valve covers and send them my way? My car could use a nice set like those

Ok I'm lost here. I thought the CR7 was using the high performance supercharged version of the 5.5 LT4? Not a supercharged LS7?

It did not appear that way to me, the C7.R motor still was using LS7 stuff (at least what was displayed at NAIAS).

For example, the C7.R carries over the powertrain for the C6.R, as the GT rules limit the maximum displacement to 5.5L, and prohibit forced induction. By comparison, the new Z06 boasts a supercharged 6.2L engine estimated at 625 horsepower. Both engines, however, are based on the historic small block architecture.

The LS7.R was direct injection, they bored a hole down into the head on the stock ls7 castings. I would guess that the 335 stamped on the head means that it's 335cc.
